One interfaces, two IP (alias), server 14.04, two gateway via routing

[sys.adimix]

I just found out

sudo /etc/init.d/networking restart

is not working anymore in ubuntu 14.04. Since I use server version, and configured it through ssh, there is no network-manager or NetworkManager for me. Instead I use

sudo ifdown eth0 && sudo ifup eth0

to restart networking.

I have two gateway, one 192.168.0.1, a router connect to broadband internet and wireless bridging to the next building. The wireless AP Client Router IP address is 192.168.200.12 in my network. As client AP from the next building, this router geting manual IP 192.168.100.12. Network in the next building is setup with IP address 192.168.100.0/24 and the the next building wireless AP is 192.168.100.11.

So here is my network configuration in /etc/network/interfaces

auto lo
iface lo inet loopback

auto eth0
iface   eth0 inet static
address 192.168.0.8
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
dns-nameservers 192.168.0.1
post -up route add -net 0.0.0.0 netmask 0.0.0.0 gw 192.168.0.1
route add -net 192.168.100.0 netmask 255.255.255.0 gw 192.168.200.12

auto eth0:1
iface   eth0:1 inet static
address 192.168.200.8
netmask 255.255.255.0
broadcast 192.168.200.255

After i restart the network, here the result from ifconfig and netstat -r -n

Only one routing command is applied after ifup. Everytime the server boot, I have to add the second gateway manually.

What is the mistake that I make in my configuration?

Most of the post is either dealing with alias, multiple network card or dealing with multiple gateway only. Does the second route command (gateway 192.168.200.12) is not working because I'm using alias IP address?

Thanks for any response.

ps:

sudo ifconfig eth0 down && sudo ifconfig eth0 up

remove my routing table, there will be no gateway if I restart networking using this command.

My currently /etc/network/interfaces. Its working after I fix some typo in previous post. Thread will be mark solved. Also as note, I assign reserve IP address in DHCP server for the my Ubuntu server MAC address.
